Answer:

b(-2)=19

b(0)=18

b(5)=15.5

Step-by-step explanation:

You substitute all x values with the number stated in each question.

Example= b(-2) --> 18-0.5(-2)

[tex]s=(\frac{1}{2} p)(l)[/tex]

Flip equation:

[tex]\frac{1}{2} lp=s[/tex]

Divide both sides by p/2:

[tex]\frac{1/2lp}{p/2} =\frac{s}{p/2}[/tex]

[tex]l=\frac{2s}{p}[/tex]

1. The value of t in the triangle is 50°

2. The value of x in the triangle is 107°

It should be noted that the total sum of the angles that are in a triangle is 180°.

Therefore, the calculation of the angles will be illustrated thus:

1. 2t + 12 + t + 18 = 180°

3t + 30 = 180°

Collect like terms

3t = 180° - 30°

3t = 150°

Divide through by 3

3t/3 = 150° / 3

t = 50°

2. x + 30° + 43° = 180°

x + 73° = 180°

Collect like terms

x = 180° - 73°

x = 107°

Answer:

B

Step-by-step explanation:

The numeric value of the expression 16 + 4(3q + p) when q = 6 and p = 2 is given by: 96.

To find the numeric value of a function, we replace each instance of the variable in the function by the desired value. This also works for multi-variable functions or expressions, as each instance of each variable will be replaced by their attributed values.

For this problem, the expression is given by:

16 + 4(3q + p)

The attributed values are given by:

q = 6, p = 2.

Hence the numeric value of the expression is found as follows:

16 + 4(3 x 6 + 2) = 16 + 4(18 + 2) = 16 + 4 x 20 = 16 + 80 = 96.

g(-9)+h(-9)=59

the answer is B

Answer:

Clearly, the given sequence is an AP with first term a=2, common difference d=5 and n=10.

Now,

s10 = 10/2 (2a + 10-1d)
=5(2x2+9x5)

=245

Step-by-step explanation:

Answer:

S₁₀ = 245

Step-by-step explanation:

the sum to n terms of an AP is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

here a₁ = 2 and d = a₂ - a₁ = 7 - 2 = 5 , then

S₁₀ = [tex]\frac{10}{2}[/tex] [ (2 × 2) + (9 × 5) ]

      = 5(4 + 45)

      = 5 × 49

      = 245

a) The problem is in the second step, the square root can't be distributed under sum.

b) 10*√41

a) The incorrect step is the second one, the square root can't be distributed like that.

Here we have the numeric expression:

5*√164

And we want to simplify it.

We can write:

5 = √25

Then:

5*√164 = √25*√164 = √(164*25) = √4,010

Now we can decompose this as a product of square numbers:

4,010 = 4*1,025 = 4*25*41

Then we rewrite:

√4,010 = √4*√25*√41 = 2*5*√41 = 10*√41

Answer:

Lowest to highest

7/10 ,  11/15,   4/5

Step-by-step explanation:

Probably the easiest way to do this is to convert each of the fractions to decimals which will clearly indicate which is the highest and which the lowest etc.

4/5 = 0.80

11/15 = 0.73

7/10 = 0.7

0.7 is less than 0.73 is less than 0.80
So 7/10, 11/15, 4/5

However, I am assuming they want you to work with fractions

To compare fractions you have to get all the denominators equal and then compare the numerator

To get a common denominator find the Least Common Multiple of the denominators. This is the lowest number that can be divided by all three denominators

Looking at 5, 15 and 10 we can see that 30 is divisible by each denominator. So that becomes our common denominator

Now multiply each fraction denominator by a factor to make the denominator equal to the common denominator. At the same time multiply the numerator by the same factor

4/5 = (4 x 6) / (5 x 6) = 24/30    Highest

11/15 = (11 x 2) / (15 x 2) = 22/30

7/10 = (7 x 3) / (10 x 3) = 21/30      Lowest

Looking at the numerator alone we can see that 7/10 is the lowest, 11/15 is next lowest and 4/5 the highest

The probability of getting both the card with same color is 0.245

Total No. of cards in a deck = 52

The cards having the same color (either black or red ) = 26 out of 52

                      which is 26/52

The probability of finding a card having the same color without a replacement

                        P = 26/52 x 25/51

[∵ After taking one card, the total no . of cards will be 51 and the card having the same color is 25]

                           = 1/2 x 25/51

                           = 0.5 x 0.49

                        P = 0.245098

Therefore, the probability that both cards are the same color is 0.245098

We need to round off it to three decimals, Thus

You can Find the Mean of a set of numbers by adding them all up and then dividing that number by the amount of numbers in the set.

72 + 75 + 68 + 84 = 231

231 / 4 = 57.75

This is his current mean.

Let's add his next score.

7 × 12 = 72 satisfies the closure property of multiplication, the other integer when the sum is - 38 and one integer is - 22 will be - 16 and the total score for Gopi will be 112 marks.

1)

Closure property of multiplication:

It states that if  two real numbers a and b are multiplied, then the product will be a real number as well.

We have 7 × 12 = 72

7, 12 and 72 all are real numbers.

So, it is a closure property under multiplication.

2)

Sum = - 38

a = - 22

We need to find b

a + b = - 38

- 22 + b = - 38

b = - 38 + 22

b = - 16

3)

1 correct answer = 4 marks

1 incorrect answer = - 2 marks

Number of correct answers = 32

Number of incorrect answers = 8

Total score = 32 × 4 + (- 2) × 8

= 128 - 16

= 112 marks.

Therefore, we get that, 7 × 12 = 72 satisfies the closure property of multiplication, the other integer when the sum is - 38 and one integer is - 22 will be - 16 and the total score for Gopi will be 112 marks.

By solving using given linear equation f(x)=x2-7 and g(x) = 2x + 9 we get  the desired value as ( g - f )(-2) = 32 .

An equation is deemed to be linear when the maximum power of the variable is consistently 1. It is also known as a one-degree equation. A linear equation with one variable usually has the form Ax + B = 0. In this scenario, the variables x and A are variables, whereas B is a constant.

A linear equation in two variables is of the form Ax + By + C = 0, in which A and B are the coefficients, C is a constant term, and x and y are the two variables, each with a degree of 1.

For example, 7x + 9y + 4 = 0 is a linear equation in two variables. If we consider two such linear equations, they are called simultaneous linear equations.

Simplification:

f(x)  = x2 - 7

g(x) = 2x + 9

( g - f )(-2) = (2x-7-2x -9)(-2)

                = -16 * -2

                = 32 .
